            Bug ID: 16849
           Summary: getaddrinfo returns EAI_NONAME instead of EAI_AGAIN
                    for network failures
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: network
          Assignee: siddhesh at redhat dot com
          Reporter: siddhesh at redhat dot com

When a DNS query fails due to a network failure, the failure is considered
transient for AF_INET and AF_INET6 lookups and hence EAI_AGAIN is returned. 
However, when the new AF_UNSPEC support was added (by using gethostbyname4_r),
the returned error is EAI_NONAME.

Patch coming up.

commit cf26a0cb6a0bbaca46a01ddad6662e5e5159a32a

    Return EAI_AGAIN for AF_UNSPEC when herrno is TRY_AGAIN (BZ #16849)

    getaddrinfo correctly returns EAI_AGAIN for AF_INET and AF_INET6
    queries.  For AF_UNSPEC however, an older change
    (a682a1bf553b1efe4dbb03207fece5b719cec482) broke the check and due to
    that the returned error was EAI_NONAME.

    This patch fixes the check so that a non-authoritative not-found is
    returned as EAI_AGAIN to the user instead of EAI_NONAME.
